ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Detailed product information



Handling information

Handling procedure
1. Open vial according to enclosed instructions.

2. Under anaerobic conditions, withdraw 0.5 ml of the recommended broth from a single test tube (5 to 6 ml) and rehydrate the entire vial contents.

3. Aseptically transfer this aliquot back into the broth.  Additional tubes of broth may be inoculated with 0.5 ml each from the suspension, and 0.1 ml may be inoculated onto a slant.  Streak several blood plates to check for colonial morphology and purity.

4. Incubate tubes under an anaerobic atmosphere at 37oC.  Incubate one agar plate anaerobically and one in air.

5. Within 48 hours, growth is evident by turbidity and smooth sediment in the broth and by colonies on the anaerobic agar surfaces.  On #260 agar, colonies are small, circular, with an entire margin, convex elevation and smooth glistening surface.  No growth should occur on the plate incubated in air. Cells are large cocci occurring singly and in pairs.


        Anaerobic conditions for transfer may be obtained by either of the following:

·Use of an anaerobic gas chamber, or

·Placement of test tubes under a gassing cannula system hooked to anaerobic gas.

·Use of stoppered tubes with transfer by syringe.

        Anaerobic conditions for incubation may be obtained by any of the following:

·Loose screw caps on test tubes in anaerobic chamber,

·Loose screw caps on test tubes in an activated anaerobic gas pack jar, or

·Use of sterile butyl rubber stoppers on test tubes so that an anaerobic gas headspace is retained.

Handling notes
On #260 agar, colonies are small, circular, with an entire margin, convex elevation and smooth glistening surface.  No growth should occur on the plate incubated in air. Cells are large cocci occurring singly and in pairs.
